The first production release of Lightning/2000™ was version 1.0.4 on
September 7, 1999. Here's what's happened since then:
 | v4.5.4, February 14, 2008
 | The custom summary language was improved to allow for much greater
flexibility and precision. |
| A minor initialization problem that sometimes could occur when using
the PCI StormTracker was corrected. |
| Ensure that the squelch is properly set when starting the application. |
| A #Sound command was added to the custom summary language. This
allows the user to cause any sound to be played, depending on the
conditions defined in the custom summary template. |
| The custom summary template may now be edited by right-clicking in the
Custom Summary window. |
| A problem with the playback of recent lightning activity was fixed. |
|
| v4.4.9, December 19, 2007
| If you use the StormTracker PCI card, you can now install the latest device driver from Boltek. You do not have to uninstall the old driver. If both drivers are detected, the latest one will be used. The latest driver for the PCI card may be downloaded from the Boltek website. |
| We've added the ability to remove the title bar from any or all of the windows in Lightning/2000. |
| In addition to the old default arrangement of the display, there are now two new options. Choose "Window | Arrange" from the main menu to select one of these.
Those pesky icons at the bottom of the screen are now hidden from view automatically. |
| There is now a #BackgroundColor command in the custom summary. With this, you can change the color of the custom summary window to indicate dangerous conditions.
A bug was fixed that sometimes caused storms' ranges to be greater than they should have been. |
| A bug was fixed that prevented flashes from being exported into the Google Earth format when using the LD-250. |
| A bug was fixed that prevented flashes from being exported properly when the decimal point on your computer was not the period. |
| Added 3 new operators to the custom summary: <>, >=, and <= (not equals to, greater than or equals to, and less than or equals to). |
| A keyword (instead of just a number) can now be used as the object of a comparison in the custom summary. |
| The custom summary processor was re-engineered for maximum efficiency.
36 new keywords were added to the custom summary to permit access to the daily record values. |
| An auto-zoom function was added. This allows any (or all) of the map windows to automatically zoom (every 5 minutes) to show most or all lightning activity. |
|
| v4.3.5, November 12, 2007
| Fixed a problem that caused the coordinates dialog to not appear when
using the Google Earth export function. |
| Fixed an anomaly with how the clock is drawn. |
|
| v4.3.2, November 7, 2007
| You may now export flashes from your archive files into a format that
can be read by Google Earth. |
| Fixed a bug that sometimes would cause the wrong stroke type
checkboxes to be checked in the Control Panel. |
| Added a "Test" button to the Email Dialog. |
| The Custom Summary can now be automatically generate an email, based
on whatever criteria you choose. |
| Reflected strokes are now placed into the correct flash, rather than
simply being discarded. |
| Screen capture, FTP, and email settings are now retained when
switching from flash mode to stroke mode or vice versa. |
| The clock is now displayed on one line, if space permits. |
| The counters now occupy a larger portion of their panels. |
|
| v4.2.2, August 3, 2007
| Optimized memory usage to avoid unnecessary reallocation of large blocks of memory used for drawing strokes. |
| The flash or stroke preferences are now always saved when switching between flash and stroke modes. |
| Control Panel's checkboxes now reflect the correct stroke type selections. |
| The labels on the Storm Statistics window's stroke type bar graph are now correct in flash mode. |
| Fixed a bug in the recent activity playback that prevented it from working correctly at all times. |
| Added the Custom Summary window. The contents of this text window are
controlled by a template file that you can change to produce virtually any information. |
| The General Status Line is now also driven by a template. |
| The Email Dialog now allows you to send any of the text windows as the body of the email. |
| You can now attach any or all of 6 screen capture images to an automatically generated email. |
| There have been some important improvements in the range determination process. |
v4.1.6, June 11, 2007
| A glitch in the screen capture of the Real-Time Lightning window could
be caused by changing colors of one of the window elements, and has been
corrected. |
| The screen capture of the Threat Assessment window sometimes showed
storms at a distance greater than their actual distance. |
| The range scaling settings are now retained when switching between
stroke mode and flash mode. |
| A problem was fixed that could cause the graph to display wildly
incorrect values for the strong flash count. |
| The "File | View | Recent archive" menu selection was added. |
| A problem was corrected that could cause slightly incorrect flash
totals to be tabulated when restarting the application. |
| The text "strong strokes" was changed to "strong
flashes" on the status line alert. |
|
| v4.1.0, May 25, 2007
| More accurate determination of a flash's bearing and amplitude.
One side-effect of this improvement is more accurate range
determination. |
| Strong flashes are now tabulated rather than strong strokes. |
| The Threat Assessment window has been significantly improved. It
now seems to be a more meaningful and accurate assessment of storm
activity. |
| The reflection rejection logic has been completely overhauled,
resulting in improved accuracy and performance. |
| Changes to the reflection rejection level now show up immediately in
the Real-time Lightning window. |
| Improved performance in the flash determination logic. |
| Storm Statistics may now be displayed by clicking in either the Threat
Assessment or Raw Lightning Data windows. |
|
| v4.0.2, October 7, 2006
| The major change involved the move from a stroke-based system to a
flash-based system that is far more reflective of reality. By more
accurately mirroring what is really happening in a storm, we will be
able to provide more meaningful and accurate information to the user. |
| Automatic screen captures can now be performed for any of the windows
in Lightning/2000. |
| New approach to the Threat Assessment window should result in a more
meaningful depiction of storm activity. |
| The stroke rate graph has been totally overhauled. It is now
possible to easily display a graph showing flashes, strokes, or other
information. |
| Far less reliance on the operating system's memory allocation
techniques means increased reliability and the ability to process more
data, faster. |
| Addition of the Control Panel for fast access to commonly used
functions. |
|
| v3.5.6, August 19, 2006
| Some LD-250 users were having problems getting a reliable COM
port connection to the hardware. This has been corrected. |
|
| v3.4.4, August 15, 2004
| Support for additional COM ports was added. |
| A bug was fixed that sometimes (rarely) could cause the stroke rate
graph to be devoid of data. |
|
| v3.4.1, July 17, 2004
| A bug was fixed that could cause the CG Flash rate and CG Flash total
records to be computed incorrectly. If you suspect your CG flash
records are incorrect, download this file.
Unzip the file and double-click on it to reset those two records. |
|
| v3.4.0, July 1, 2004
| New email options to only send a brief summary, and to only send an
email when a specified stroke rate is reached. |
| The stroke rate activity graph can now be automatically captured and
uploaded to your website. |
